Zusammenfassung:	Disclosed is a vessel for reducing an organic vibromotive force of propeller cavitation. The vessel for reducing an organic vibromotive force of propeller cavitation according to an embodiment of the present invention comprises: a working gas accommodation membrane pad which is coupled to a hull adjacent to a propeller, and in which working gas, which generates incident waves generated due to the rotation of the propeller and reflected waves to cause destructive interference, is accommodated on one side thereof; and a working gas volume control unit which is connected to the working gas accommodation membrane pad, and controls the volume of the working gas accommodated inside the working gas accommodation membrane pad in order to variably control frequency band changes according to a change in the revolutions per minute (RPM) of the propeller. 프로펠러 캐비테이션 유기 기진력 저감형 선박이 개시된다. 본 발명의 일 실시예에 따른 프로펠러 캐비테이션 유기 기진력 저감형 선박은, 프로펠러에 인접된 선체에 결합되며, 프로펠러의 회전 시 발생되는 입사파와 상쇄간섭(Destructive Interference) 현상을 일으키기 위한 반사파를 발생시키는 작업기체가 일측에 수용되는 작업기체 수용 멤브레인 패드; 및 작업기체 수용 멤브레인 패드와 연결되며, 프로펠러의 회전수(RPM) 변화에 따른 가진 주파수 대역 변화에 대해 가변제어할 수 있도록 작업기체 수용 멤브레인 패드 내에 수용되는 작업기체의 부피를 조절하는 작업기체 부피 조절부를 포함한다.
